Requires:

"Grapple",
"f_DefeatedPhantoon"

Jump across the first platforms. It is fine to jump from them when they are a bit submerged. Get a bit of run speed on the final platform, and wall jump if necessary. When accidentally falling off the platforms, it may be best to take a spike hit and climb the left wall.

Requires:

"Gravity",
"canWallJump",
"f_DefeatedPhantoon"

Jump onto the first platform, which is easiest when the water is low. Continue jumping on the platforms to prevent them from going into the water. Get a bit of run speed on the final platform, which is easiest while the water is low, then jump to the solid ground.

Requires:

{"disableEquipment": "HiJump"},
{"or": [
  "canMoonwalk",
  "canTrickyJump"

"f_DefeatedPhantoon"

From a standstill at the door, jump just before the first step. Do a lateral mid-air morph and bounce on the first platform. This should bounce on the third platform and get to the item.

Requires:

"canSpringBallBounce",
"f_DefeatedPhantoon"

Use a mid-air horizontal bomb boost to reach the first platform. Jump across to the last platform. Wait until the water is low, let the platform sink slightly, then jump and horizontal bomb boost to the item.

If HiJump is available, then it is possible to simply spin jump from the underwater platform to the first moving platform. If HiJump cannot be disabled, then the bomb boost from the last platform is more difficult: in this case Samus must jump, lay the bomb on the way down, then jump again to a precise height and morph to get the boost.

Requires:

"f_DefeatedPhantoon",
"canJumpIntoIBJ",
"canBombHorizontally",
"canTrickyJump",
"h_complexToCarryFlashSuit"

Use a mid-air horizontal Power Bomb boost to reach the first platform. Jump across to the last platform. Wait until the water is low, let the platform sink slightly, then jump and horizontal Power Bomb boost to the item.

If HiJump is available, then it is possible to simply spin jump from the underwater platform to the first moving platform, saving a Power Bomb. If HiJump cannot be disabled, then the Power Bomb boost from the last platform is more difficult: in this case Samus must jump, lay the Power Bomb on the way down, then jump again to a precise height and morph to get the boost.

Sink on the platform until it on or near the floor, then gravity jump.

Requires:

"f_DefeatedPhantoon",
